How the DGT's position has evolved
Current position
If the withholding was not applied or was lower than required due to reasons attributable to the withholding agent, the recipient may deduct from their tax liability the amount that should have been withheld pursuant to article 99.5 of the LIRPF (Personal Income Tax Law). Failure to comply with the obligation to withhold does not allow the withholding agent to make deductions from the worker's income or to claim the unwithheld amounts in a tax context. In the case of public sector remuneration, only the amounts actually withheld may be deducted.
The DGT's position has remained constant since 2014, reaffirming the recipient's right to deduct what should have been withheld due to the fault of the withholding agent. The doctrine has maintained the impossibility of the withholding agent passing the tax error on to the worker. Clarifications have been added regarding the exclusion of public sector remuneration and the use of Tax Agency tools for calculation.
